Wreath of Orange Cinders

You brandish the melee weapon used in the spell’s casting and make a melee attack with it against one creature within the weapon's reach. For this attack, you can choose to use your spell casting ability modifier for the attack and damage rolls instead of Strength or Dexterity. On a hit, the target suffers the weapon attack’s normal effects, and you can cause dazzling orange sparks to explode from the blade, showering them in hot sparks dealing fire damage equal to your spell casting ability modifier.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d10 fire damage, additionally it deals 1d6 fire damage to a second creature within 5ft of the original target. Both damage rolls increase by 1d10 and 1d6 respectively at 11th level (2d10 and 2d6) and 17th level (3d10 and 3d6).
